My invention relates to improvements in ventilating windows and the like.

An important object of the invention is to proj vide a Ventilating window particularly well adapted to be installed in `sets or grol'l'psI to provide adequate ventilation along the ent-ire side' of a porch, sun parlor or the like'.

A further object is to provide Ventilating windows of the above-mentioned character., together with novel andV highly simplified operating mechanism for opening and closing ai group of the windows in unison.

A further object is to provide windows oi' the above-mentioned character wherein no frames are needed between the sash of the windows, and accordingly better ventilation and fuller visibility" are alforded by the windows, wherever they areinstalled.

A still further object of my inventitmv is to pro-V vide Ventilating Windows of the above-mentioned character and operating mechanism therefor, the arrangement being highly simplied, compact, strong and durable and relatively inexpensive to manufacture.

Other objects and advantages of the inven'; tion will be apparent during the course of the fol lowing description. y

In the accompanying drawings forming a `pai/t cf this application, and in' which like'rnuinerals are employed to designate like parts throughout the same:

In the drawings, where, for the purposev of l thereof,

Figures 1 to 8, inclusive, wherein the numeral I5 designates generally aside of a porch or room provided with a large, rectangular opening I6 extending for substantially the entire length of the side I5, and bounded at its bottom with an elongated, horizontal window sill I1. The top of the large, rectangular opening I6 is bounded by a horizontal, yelongated header I8, and the opposit-eA ends of the opening are bounded by vertical frame sides or railsv I9.

In order to provide a Ventilating closure for the opening I5 which will aiord a maximum. of visibiiity, aswell as adequate ventilation, I mount within the opening I6 a plurality of vertically elongated, relatively narrow, rectangular window sashes 2). The window sashes 20 are preferably arranged in groups of six, although this number may be varied, and each group of sashes 2u operates inv unison for opening and closing the opening I, as will be more fully described. Of course, if the opening I6 is small enough so that one group of six of .the window sashes 2U will 'oe sufiicient to completely cover it, only one such group will be employed, and a single group of sashes 2li comprising more or fewer than six sashes may be employed when necessary. In Figures 1 and 2 of the drawings, one group of the Window sashes 2) is illustrated for covering the opening IG, and this group comprises the correct number of window sashes, such as six.

Each` window sash 25 in the group of window sashes comprises an outer, rectangular frame or sash including top and bottom, horizontal sash members or' bars 2| and 22, and sides 23, and 24.

No individual frames or vertical separating posts are required between the individual window sashes 2e of the group, and the sides 23 and 24 of each Window sash are longitudinally grooved in their inner and outer faces, respectively, as shown at 25'and 2B, for forming outer and inner tongues 2'I and 26 which intert with like tong-ues formed upon the next adjacent window sash. With this arrangement, the sides of adjacent window sashes 2 overlap, as shown in Figure 2, when the Window sashesfof the group are closed, and no individual window frames are needed.

Adjacent to the top and bottom rails 2I and 22 of each window sash 29, and near the side 24 l plates 29 and 35 are recessed or morticed .litnin the bottom and top faces,`re spectively, of the header I8 and sill I'I. The plates and :is are thin and rectangular, and are rigidly secured to the header I8 and sill Il by screws SI or the like. The plate 29 has a centrally disposed, depending dowel 32 rigidly se- 3 cured to its bottom face and projecting below the bottom face of the top rail I8. The plate 30 has a similar upstanding dowel 33 rigidly secured to its top face and projecting above the top face of the window sill I'I. The dowels 32 and 33 are arranged in vertical alignment. Recessed or morticed within the top and bottom faces, respectively, of the bars 2| and 22 of each window sash 25 are elongated, rectangular hinge plates 34 rigidly secured to the bars 2| and 22 by means of screws 35 or the like. The hinge plates 34 are provided with central openings 36 receiving therein the dowel pins 32and 33. bearings 3l are mounted upon the pins 32 and 33 and arranged between the pairs of plates 29 and 34 and 30 and 34, to facilitate the free horizontal swinging movement of the sashes 2B when the same are opened and closed. The hinge plates 34 l are iiush with the top and bottom edges of the window sashes 20, and adapted to swing freely adjacent to the bottom face of the header I3 Y and the top face of the sill Il, respectively. Each hinge plate Y34 has an integral, laterally inwardly projecting, inclined extension or arm 38 having an aperture 39 in its inner end for receiving a pivot pin 4B, pivotally connecting the arms 38 of the hinge'plates with a common, longitudinally extending, horizontal, elongated, connecting rod 4I extending adjacent to the inner sides of the window sashes 20 at the tops and bottoms of the windowsashes. The connecting rods 4I at the tops and bottoms of the window sashes 23 thus serve 'to operatively connect the window sashes 0I" the grouptogether through their arms 38, so that they may be opened and closed in unison.

The bottom connecting rod 4I, only, adjacent to one end thereof is pivotally connected with an intermediate, relatively short, horizontally swingable connecting rod or link 42 arranged above the window sill .Il inwardly of the sashes 2,.and in turn pivotally connected at its opposite end, as shown at 43,'with one end of a horizontally swingable crank arm 44 having its opposite and inner end pivotally connected, as at 45, with the top end ofa vertically disposed shaft 46 projecting through the top of a small, rectangular housing or regulator casing 41 rigidly mounted upon the top face of the window sill I1 adjacent to one end sash 26 in the group of sashes. The shaft 46 extends vertically through the housing 4l and has a gear 48 mounted thereon andarranged within the housing for rotation therewith. This gear 48 meshes with and is driven by a worm gear 49 secured to a horizontally disposed shaft 50 projecting through the rear vertical side of the housing or casing 41 for connection with a crank handle I which is operable for driving the gears 48 and 49 to swing the arm 44 horizontally in both directions. By operating the crank 5I, it is thus possible through the crank arm 44, link 42 and elongated connecting rod- 4I at the bottom'of the windows to open and close the sashes 20 of vthe group in unison. By virtue of the additional connection between the sashes 2o at their tops through the mediumof thetop connecting rod 4I and associated Yelementsjthe sashes 20 of the group are connected in a very strong and durable manner. Accordingly, forces. such as those exerted by the wind, will'not tend to spring or otherwise damage the sashesor their hinged connections with the header `I3 andsill Il. lWith the arrangement provided, itispossible to open the sashes 20 of the group until they are arranged substantially at right angles tothe Asides I5 of the porch, and in this position'the Brass washers or thrustV 4 opening I6 will be substantially entirely uncovered for affording maximum ventilation and visibility. As previously stated, there are no individual window frames or uprights between the adjacent sashes 20 oi the group.

In Figure 9, I have shown a slight modication of my invention, wherein elongated or taller sashes or ventilators 52 are provided, and these sashes or ventilators 52 are preferably of the height of doors generally employed upona house. It may be desirable to install groups of the sashes or ventilators 52 upon opposite sides of a door at one end of a room or porch. Such groups of the ventilators 52 are to be operated simultaneousiy, generally in the manner that the sashes 20 of the rst form of the invention are operated. Two or more of the ventilators 52 may accordingly be connected or coupled together for simultaneous operation in generally the same manner that the sashes 20 are connected for simultaneous operation.

In the form of the invention shown in Figure 9, a lower floor level sill or rail 53 is provided, and this rail 53 receives the lower dowel plate 30, carrying the lower upstanding dowel pin 33. The plate 30 is ush with the top face of the rail 53. The upper dowel plate 29, not shown, is mounted in a suitable header in exactly the same manner that the dowel plate 29 is mounted upon the headerv I8 in the first form of the invention. Likewise, one hinge plate 34 is mounted flush with the top bar 54 of the ventilator 52 and the bottom hinge plate 34 is secured .to the bottom bar 55 of the ventilator 52 in the identical manner in which the plate 34 is secured to the bottom bar 22 of the sash 20. The ventilators 52 are substantially taller than the sashes 20, and accordingly, a fixed, elongated, horizontal rail 56 is provided near the vertical centers of the ventilators 52 /and provided in their outer sides with arcuate notches 51, forming clearance for the inner sides of the ventilators 52 to swing through. The regulator casing '41 is `mounted upon the intermediatehorizontal rail 56, adjacent to the end ventilators 52 of the group. The regulator for opening and closing the ventilators 52 is substantially identical with the regulator for opening and closing the sashes 20, except that the vertically disposed shaft carrying the gear 48 is elongated vertically and extends above and below the regulator and above and below the intermediate rail 56, .as shown at 46. rIfhe same crank handle 5I is provided, asV in the first form of the invention. for operating the regulator to impart rotation to the vertical, elongated shaft 46. The shaft 46 extends adjacent to the top and bottom Vedges of the ventilators 52 and has rigidly secured, as by welding, to its top and bottom Vends horizontally swingable crank arms 58. Pivotally connected, as at 59, with the free ends of the crank .arms 58, are intermediate, horizontally swingable links or rods 68. The opposite ends of the links Ell-are pivotally connected, as at 6I, with the .adjacent ends of the top andbottom elongated, horizontal connecting `rods 4 I. These connecting rods 4I are disposed adjacent to the top and bottom edges of the ventilators 52 the same manner that they are disposed adjacent to the top and bottom edges of the sashes 20. The inwardly or rearwardly extending horizontal arms38 of the hinge plates 34 are pivotally connected, as. at 62, with the top and bottom connecting rods 4I at longitudinally spaced intervals along the connecting rods. Accordingly, the ventilators 52 are swung horizontally from opened to closed positions by the operation of the cranks 5I in the same manner that the sashes of the first form of the invention are operated. However, in the form of the invention shown in Figure 9, the elongated, vertical shaft 40, crank arms 58 and associated elements are operatively connected with the ventilators 52 at both their top and bottom ends, so that the opening and closing eiort is applied to the ventilators 52 at their top and bottom ends. This is a stronger construction and is necessitated by the fact that the ventilators 52 are substantially longer or taller than the sashes 20. Otherwise. there is substantially no difference between the construction or operation of the ventilators 52 and sashes 20. Both arrangements are simplified, compact and very strong and durable.

It is to be understood that the forms of my invention herewith shown and described are to be taken as preferred examples of the same, and that various changes in shape, size and arrangement of parts may be resorted to without departing from the spirit of my invention or the scope of the subjoined claims.

Having thus described my invention, I claim:
